NobTra Infrared Gate Opener Sensor, (also called electronic grating or infrared fence) (also called "infrared railing") is a kind of active infrared beam, which uses multiple infrared beams to beam, and the transmitter sends "low frequency emission and time division detection" to the receiver. When a person or object blocks any two or more adjacent beams of light emitted by the transmitter for more than 2 seconds, the receiver immediately outputs an alarm signal. When a small animal or a small object blocks one of the beams of light, the alarm No alarm signal will be output.


Application: Infrared Gate Opener Sensor is a new front-end product for home anti-theft care windows and balconies that replaces "iron cage" and traditional door and window magnetic control switches, curtain detectors and other products used in traditional technical defenses. It forms a function with various anti-theft alarm controllers. Powerful anti-theft alarm system. According to its working principle, it can also be expanded for multiple purposes, such as vehicle detection at the entrance and exit of an indoor parking lot.
